ZSNES is a Super Nintendo emulator written mostly in x86 assembly (59.6006%), and a little C and C++. Because of this, ZSNES cannot be ported to any non-x86 compatible operating system or console. A few examples of incompatible operating systems and consoles (it is not limited to those on this list):

At the time of this post, ZSNES has been ported to all compatible operating systems and consoles. Any posts requesting new ports of ZSNES will be locked immediately. There are simply no plans to support incompatible OSes and don't bother asking.
